Re: Home / Limit switches

Someone pointed out a while ago that it would be a bit better if the limit
switches were closed when everything was okay. A closed signal will fault
for a broken wire or connection but an open won't.

A question to the group:
I found when doing my E-stop circuitry and sequencing that it would
probably
be much simpler if I threw a PLC I had laying around at it. Of
course, then
I'd be relying on more software/hardware to E-stop, which is of
course, questionable
depending on the application. I used to do aerospace software, did
a lot of
fault handling stuff, and was wondering what the feelings of people
with more
CNC experience were.
